Blockade of Hypoxia: The Impact on Tumor Growth in an Experimental Tumor Model

Background: Tumor microenvironment is an active factor participating in immunoregulation, thereby preventing immunosurveillance and limiting the efficacy of anticancer therapies. Hypoxia as a major characteristic of solid tumors causes the expression of Hypoxia-Inducible Factor-1α (HIF-1α). This is a transcription factor that mediates hypoxic responses of tumor cells and involves in the express...

Rapid immunohistochemical detection of tumor cells in gastric carcinoma.

The detection of single tumor cells or tumor cell clusters represents an important issue in intraoperative frozen section analysis. For example, surgical margins may be evaluated in order to minimize the number of additional operations. Furthermore, intraoperative diagnosis of lymph node micrometastasis (LNM) may help to define the area of appropriate lymph node dissection. In addition to haema...

Immunohistochemical Detection of Cyclin A in Wilms Tumor

Introduction Cyclins displays oscillatory expression during the cell cycle. They regulate the activity of CDKs, and, together with CDKs, they form holoenzymes that phosphorylate regulatory substrates like retinoblastoma proteins (pRb) and p107 (1,2). Thus far, 14 different mammalian cyclins are known, named cyclins A-J (3). Cyclins are usually grouped into G1 cyclins, such as Cyclin E, which co...

Immunohistochemical Detection of NRASQ61R Mutation in Diverse Tumor Types.

OBJECTIVES Testing for NRAS mutation at codon Q61 is of therapeutic, prognostic, and diagnostic importance for metastatic melanoma, thyroid carcinoma, and colorectal carcinoma. Immunohistochemistry for NRASQ61R, the most common NRAS mutation, offers several practical advantages over current molecular diagnostic techniques. METHODS We investigated the sensitivity and specificity of NRASQ61R in...

Tumor Hypoxia and Blood Vessel Detection

A BSTRACT : We have developed a multistage image analysis technique for the simultaneous segmentation of blood vessels and hypoxic regions in dualstained tumor tissue sections. The algorithm, which is integrated in a task-oriented image analysis system developed on-site, initially uses the K -nearest neighbor classification rule in order to label the image pixels. Classification is based on a t...
